I’d respectfully disagree with your last para, Weegie (and wholeheartedly agree with your comment on teenagers!)
The main difference between Twickenham and Murrayfield is location, location and location.
If anyone is going to Twickenham, and either lives in the South East, or comes from farther away, it’s a sod to get to. There are buses, or the more popular Network Rail, but there are queues for both, especially when leaving the ground, that people want to avoid.
I had difficulty in getting on a train at Clapham Junction yesterday just after 12.00, with the numbers going. (for the uninitiated, CJ is a rail hub where trains from a number of mainline stations such as Waterloo and Victoria pass through.) It was pretty impossible for anyone on subsequent stations to Twickenham to get on at those stations. So people know to arrive early, and there are far fewer pubs in the local area to meet up with friends. For Murrayfield, Edinburgh city centre is your oyster to meet and then even walk to the ground from the west end.
Similar happens at the end of the match. With so many people going, its usual to meet up with others after the match in one of the Twickenham bars, rather than all trying to head off in different directions and this also has the benefit of letting the crowds for the trains die down. Last night I left for Twickenham station at about 8, and still was corralled into long queues at the station to get a train back to London. From joining a queue, to getting on a train, was probably about 20 mins. I only saw a couple of drunks, but it may just have been the time I went there and left.
I’d agree that there’s more scope for corporate hospitality at Twickenham, as the local area population is so much larger. It’s the same with the concessions – if there was a throttled transport system to get to Murrayfield and nothing in the immediate area, I’d imagine it would be the same. A pint of my usual in a London postcode still costs me more than a fiver, so the stadium price supplement is not outrageous. I’m not shocked to pay £45 for a ticket to see the Sarries Glasgow match in an area of the ground that would probably be a bronze ticket at Murrayfield for an international. It’s nothing to do with the middle classes v. ordinary fans, just that there’s a bigger potential audience. And despite contacts in London, and none in Edinburgh, I still find it far easier to get tickets for Murrayfield than Twickenham. One thing that does strike me though, there are far more under 25s going to Murrayfield. I hope that’s a good thing.
I console myself with the thought that I must have been really bad in a previous life for me to come back in this one and have my punishment as a supporter of the Scotland rugby team.
